 The southwest of the region is part of the Peace Country, an area that stretches into northeastern British Columbia consisting of fertile prairie, ranchland, and farmland along the Peace River and its tributaries.Northern Alberta is crossed by the Peace River and the Athabasca River, both of which eventually convene to form the Slave River that ultimately drains into the Arctic Ocean via Great Slave Lake and the Mackenzie River within the Northwest Territories.Other major rivers are Wapiti, Smoky, Hay, Chinchaga, Petitot Rivers in the west, Wabasca River in the center and Firebag and Clearwater River in the east.
